PENHOLDER.

Application filed November 16, 1912.

To all fro/wm it may concern:

Be it known that l, JOHN T. MCKITTRICK, a citizen of the United States, residing at Fort Madison, in the county of Lee and State of lowa, have invented new and useful lmprovements in Fenholders, of whichv the following is a specification.

My invention relates, broadly, to the class of penholders and more specifically to that class of penholders which are provided with means for facilitating the attachment and detachment of pen points to and from the same.

The object of my invention is designed to overcome the difliculty heretofore existing in this art and for the prevention of the soiling of the lingers of the operatonthe characteristics of economy and durability having been taken thoroughly into consideration.

With the above and other objects in view, my invention relates to such details of construction and in the arrangement and combination of the several parts as will be hereinafter fully described and specifically pointed out in the appended claim.

ln describing my invention in detail, refn erence will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure l is a side elevation of my invention. Fig. 2 is a. longitudinal sectional view showing the parts in elevation. Fig. 3 is a side elevation of my invention showing the locking member out of engagement with the sliding sleeve. Fig. 4 is a perspective view of the locking member. Fig. 5 is a perspective view of the sliding sleeve. Fig. 6 is a view similar to Fig. 5, however, the sleeve is shown in a reversed position, and Fig. 7 is a fragmentary view of the handle of the pen.

In the accompanying drawings wherein is illustrated the preferred form of myinvention, the numeral l designates the handle of an ordinary penholder, the forward end of which is provided with extensions 2, said extensions being spaced apart from each other and having a stud 3 journaled there` through which serves the purpose that will be hereinafter set forth. A sleeve 4L is pro vided which has a longitudinally extending slot 6 provided therein, the said slot communicating with one end of the sleeve as is clearly shown. The sleeve is also provided with a longitudinally extending openingA 6 upon one side of the same, opposite the slot Specication of Letters Patent.

y 5, however this opening is provided near the forward end of the sleeve, while the slot 5 is near the rear end. The slot 6, receives a pin 7 which is fast upon the handle of the pention of the stud and being substantially semicircular in cross section. Upon reference 'to the drawings, it will be recognized that `the forward extremity of the locking member is of greater diameter than the rear extremity thereof, so that the same will be hereinafter termed as a substantially wedge shaped member, the wedging action being hereinafter fully set forth.

Formed upon the straight upper face of the locking member is an offset portion l0 substantially semi-circular in cross section, the forward extremity thereof being flush with the forward end of the locking member, however, its rear end is beveled as shown at ll to form an inclined surface.

In the operation of my invention, the parts are disposed substantially as shown in Figs. l, 2 and 3, the locking member being pivoted to the stud 3, while the sleeve is slidably mounted upon the handle and normally covers the locking member as is clearly shown.

The slot 6 in the sleeve is preferably directly above the offset portion 10 whereby when the pen point 12 is moved into place, a slight spring action may be generated by the sleeve so that the same is securely held in position. .lf it is now desired to move the pen, the handle can be merely pushed forward in the sleeve so as to allow the locking member to tilt upon its pivot point and consequently allow the pen point to drop.

t should be particularly noted that the pen-gripping device 8 has its pen-engaging surface l0 extending parallel tothe sleeve l so that the pen will be very tightly gripped by frictional engagement. lt should also be noted that the opposite portion of the pengripping device is tapered for its full length, as shown in Fig. 2, so that when it is desired to remove the pen, and the sleeve ILM) moved rearwardly to the position shown in Fig. 3, the pen will be partially released as soon as the forward end of the pen-gripping device leaves the sleeve. This will permit the pen to be very easily released since as soon asthe sleeve is moved rearwardly, the pen-gripping device begins to drop to the position shown in Fig. 3 and this permits the pen to drop 0E the pen-gripping device.

From the foregoing, it is thought that Vthe advantagesand novel features of my invention will be readily comprehended.

It is to be recognized' that do not limit myself to the use of any particular material in the construction of my invention, nor am l limited to the use of the speciiic dimensions shown inthe drawings.

l desire it tobe understood that I may i make slight changes in the construction and in the arrangement and combination of the f several parts, .provided7 however, such changs fall within the scope yof the subjoined claim.

Having thus fullyv described my inven- Gopies of this'patent may be obtained for tion, what I claim as new and desire to secure by Letters Patent, is

A penholder comprising a handle having its inner end portion provided with a longitudinally extending slot, a sleeve slidably mounted upon said handle, means for limiting the sliding movement of said sleeve, and pen gripping means extending through said sleeve and having its inner end portion pivotally mounted in the longitudinally extend ing slot of said handle, the upper face of said pen gripping means extending parallel to said sleeve to a point adjacent said handle and being then inclined toward its pivot point, and the lower face of the pen gripping means being inclined from its outer end to the pivot point whereby the outer end portion only of the lower side of said pen gripping means will contact with said sleeve.
